I am able to get todays high / low / open with below formula correctly.
=INDEX(GOOGLEFINANCE("NSE:CIPLA", "HIGH")) // considering changing second param
but I cant get the today's close with below formula.
=INDEX(GOOGLEFINANCE("NSE:CIPLA", "CLOSE"))
it gives below error -> "Function GOOGLEFINANCE parameter 2 value is invalid for the symbol specified"
Apparently you need to specify the date and I was only able to get the close from the previous day
